Beschreibung
Zusammenfassung:	A pump group (10) of a cooling system for an engine (550) of a vehicle comprises an electric drive (4) comprising a first one-way coupling (52), a mechanical drive (5) comprising a second one-way coupling (43), and an electromagnetic pulley (51) normally engaged, electrically excitable to disengage the mechanical drive (5) from the shaft (13). L'invention concerne un groupe pompe (10) d'un système de refroidissement pour un moteur (550) d'un véhicule, qui comprend un entraînement électrique (4) comprenant un premier accouplement unidirectionnel (52), un entraînement mécanique (5) comprenant un second accouplement unidirectionnel (43), et une poulie électromagnétique (51) normalement en prise, pouvant être excitée électriquement pour dégager l'entraînement mécanique (5) d'un arbre (13).
